With the current rawhide version of oprofile, binutils and glibc opreport segfaults when using the -l option (see below) I saw in koji that the rebuild of oprofile for F11 failed. The most current working version oprofile-0.9.4-3.fc10 has the same problem as described in bug #467651 Recompiling from source (as suggested in comment #7) didn't help a lot as opreport is segfaulting now (see below) binutils-2.19.51.0.2-16.fc11.i586 binutils-devel-2.19.51.0.2-16.fc11.i586 glibc-2.9.90-8.1.i686 glibc-devel-2.9.90-8.1.i586 gdb --args opreport -l --merge tgid ... ...

I'm not able to reproduce this problem anymore. All I did was upgrading to the latest available kernel in rawhide.
Just rebuilt oprofile for F11, oprofile-0.9.4-6.fc11 (http://koji.fedoraproject.org/koji/buildinfo?buildID=97181). Could you check that this problem no longer occurs with the newer oprofile?
Yes, I just installed the latest build from koji on F10 and everything works now as expected! Thanks for your help.
